High Efficiency Power Amplifier Module FDD LTE Band 8, WCDMA Band 8

The NZ5408S is a 10-pin power amplifier module developed for FDD LTE/ WCDMA applications. With advanced InGaP HBT technology, the module supports full bandwidth of FDD LTE Band 8, WCDMA Band 8, and meets the stringent linearity requirements of LTE/WCDMA/CDMA specifications.

The NZ5408S is self contained with a GaAs power amplifier, a bias controller, input & output matching networks and internal directional coupler. The GaAs PA provides RF amplification in linear mode, while the integrated bias controller provides regulated voltage according to input control logic, which can be compatible with most of mobile device solutions. The module is fully matched to 50 ohms at all RF ports.

With Lansus's state-of-the-art technology and supporting three (high, medium and low) power modes with different gain settings, the NZ5408S reduces current consumption significantly in both high and low power operations. Furthermore, different gain steps also increase the system’s dynamic range. Compatible with APT (Average Power Tracking) technology to extend battery life, the NZ5408S efficiency can be further improved with VCC2 supplied from DC-DC converter, which can be set from 0.5~3.4V accordingly to different output power level.

Packaged in a compact 3mm x 3mm x 0.85mm module, the NZ5408S performs with high efficiency, high linearity, low temperature variation, strong reliability and robust ruggedness. In addition to the feature of RoHS compliant, the NZ5408S is free of hazardous substances and rated as green product.

The NZ5408S is rated to Moisture Sensitivity Level 3(MSL3) at 260°C per JEDEC JSTD-020.
